"Cache corruption detected" when editing CLOCK timestamp by hand

[William Denton]

Sometimes I edit timestamps by hand when I'm clocking things.  I had a task 
where I'd clocked in and wanted to close by hand (by adding --[2021 and so on to 
the CLOCK line) but when I started typing this popped up in a window:

Warning (emacs): org-element--cache: Cache corruption detected in 
work-diary.org. Resetting.
 The error was: (error #("Not an Org time string: []" 24 25 (wrap-prefix #(" 
" 0 8 (face org-indent)) line-prefix #("        " 0 8 (face org-indent)) fontified t) 25 26 (wrap-prefix #("        " 0 8 (face org-indent)) line-prefix #("        " 0 8 (face org-indent)) fontified t))) Disable showing Disable 
logging

"[2021" certainly isn't a time string, but the warning surprised me.  I presume 
it's because of the recent improvements about persistence.  I have no 
suggestions but thought I'd point it out in case it might crop up more if other 
people enter clock timestamps by hand.

Thanks,

Bill
